CARBURETER-SUPPORT.

Specification of Letters Patent.

Patented July 22, 1919.

Application led February 6, 1918. Serial No. 215,716.

To all whom it may concern:

Be it known that I, WILLIAM' G. SMITH, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Carbureter-Support, of which the following is a full, clear, and exactdescription.

The invention relates to internal combustion engines, notably such as are used on aeroplanes, motor boats and the like, and its object is to provide a new and improved carbureter support arranged to maintain the carbureter at all times right Vside up irrespective of the position the engine assumes on the tilting or rocking of the aeroplane,

motor boat or other vehicle on`which the engine is used. Another object is to insure proper delivery of the explosive mixture to the manifold of the internal combustion engine. Another object is to insure proper feeding of the gasolene from a xed tank to the carbureter. i

In order to accomplish the desired result, use is made of a supply pipe for` the passage of the explosive mixture to the manifold of the internal combustion-engine, the supply pipe ybeing made in sections connected with each other by a ball and socket joint or other universal connection, one of the sections being attached tothe manifold of the engine and the other section having attached theretothe carbureter. A l

A practical embodiment of the invention is represented in the accompanying drawings forming apart of this speciiication, in which similar characters of reference indicate corresponding parts in both views.

Figure 1 is a side elevation of the carbureter support as applied; and

Fig. 2 is an enlarged sectional side elevation of a portion of the carbureter suport. P The carbureter 10 of any approved construction is attached to the lower end 11 of a vertically disposed section 12 of a vapor supply pipe 13 for supplying the manifold 14 of an internal combustion engine with the desired combustible vapor or explosive mixture. The upper end 16 of the vertical section 12 of the supply pipe 13 is provided with the ball member 17 of a ball and socket joint 18 having its socket 19 formed on the inlet end 20 attached to the manifold 14. It will be noticed that the axis of the ball member 17 of the universal joint 18 is at a right angle to the section 12 which by the ed. Thus by the arrangement described, the

carbureter l0 is maintained at all times in proper position to insure an accurate formation of the explosive mixture and delivery of the same to the manifold 14 of the engine 15 to insure proper running of the latter. j

In order to supply the carbureter 10 with gasolene use is made of a gasolene supply pipe 30 extending from a gasolene tank and connected by a union 31 with the outer threaded end ofan entrance pipe section 33 attached to the section 20 of the vapor sup ply pipe 13 at a point intermediate the usual vapor controlling valve 34 and the ball and socket joint 18. The end section 33 extends within the section 20 and its inner end is connected by a coupling 35 with one end of a flexible pipe 36 of rubber or other suitable material and extending lcentrally through j the ball and socket joint 18 to connect at its other end by a coupling 37 with a tube 38 having on its outer end a conical head 39 seated on the corresponding seat 40 formed within a nipple 41 screwed or otherwise secured to the end 16 of the free swinging section 12 of the vapor supplypipe 13. A spring 42 abuts against the inner end of the nipple 41 and against the coupling 37 to hold the conical head 39 irmly on its seat 40 to prevent leakage of gasolene. The outer end of the nipple 41 is connected by the end pipe 44 with the carbureter 10 so that gasolene can readily iiow from the gasolene tank through lthe gasolene supply pipe to the carbureter 10 to supply the latter with gasolene. A spring 50 bears at one end against the coupling 35 and is connected at its other end with a bar 51 hung 0n pivots 52 attached to the ball 17 of the ball and socket joint 18. The bar 51 is lprovided with a central aperture 53 for the free passage of the Hexible pipe section 36. It is understod that the spring 50 presses the ball 17 in firm contact with its socket 19 to prevent erratic movement of the said ball within the socket on a quick change in the position of the aeroplane or motor boat.

Although the lower end of the vertical pipe section 12 of the vapor supply pipe 13 is weighted for the attachment of lthe carbureter l0, an additional weight 60 may be used adjustably secured by a set screw 6l on an arm 62 fastened by clamps 63 or other means to the section 12 near the lower end thereof.

Having thus described my invention, lI claim as new and desire to secure by Letters Patent l. In an internal combustion engine, a va por sup-ply pipe made in sections connected with each other by a universal joint, one of the sections being attached to the manifold of the engine, a carbureter attached to the other section, a fuel feed pipe entering one section of the vapor pipe and extending through the universal joint and the other section of the vapor pipe and connected with the carbureter.

2. In an internal combustion engine, a vapor supply pipe made in sections connected with each other by a universal joint, one of the sections being attached to the manifold of the engine and a carbureter attached to the other section, and a gasolene feed pipe supplying the said car'bureter with gasolene and made in sections, of which one is flexible land extends through the said universal joint.

3. In an internal combustion engine, a vapor supply pipe made in sections, a ball and socket joint connecting the sections with each other, one of the sections being attached to the manifold of the engine and the other section Ibeing free to swing relative to the fixed section and a carbureter mounted on the end of the said free swinging section of the'vapor supply pipe, and a gasolene supply pipe made in sections of which one is an entrance section and is attached to the said fixed vapor supply pipe section and is connected with a gasolene tank, another section is an end section Iand is connected with the carbureter and is attached to lthe said free swinging section of the vapor supply pipe, and a third section is flexible and con- Copies of this patent may be obtained for nects the said entrance section with the said end section, the said flexible section extending through the said ball and socket joint.

4. In an internal combustion engine, a vapor supply pipe made in sections, a ball and socket joint connecting the sections with each other, one of the sections being attached to the manifold of the engine and the other section being free to swing relative to the fixed section, the movable section of the joint being provided with a transverse bar, a carbureter mounted on the end of the said free swinging sectionof the vapor supply pipe, a gaso-lene feed pipe extending through the joint and formed of sections, coupled together in said joint, anda spring bearing on the transverse member of the movable men1- ber of the said ball and socket joint and a coupling of the feed pipe.`

5. In an internal combustion engine, a. vapor supply pipe made in sections, a ball and socket joint connecting the sections with each other, one of the sections being attached tothe manifold of the engine and the other section being free to swing relative to the fixed section and a carbureter mounted on the end of the said free swinging section of the vapor supply pipe, and a gasolene supply pipe made in sections, of which one is an entrance section `and is attached to the said fixed section of the vapor supply pipe and extends `into the same, another sectio-n of the gasolenepipe is an end section and connects with the said carbureter, and a third section of the said gasolene supply pipe is {iexible and extends centrally through the -saidball and socket jointfand one end` is connected With the said entrance section, a nipple held on the free swinging section of the vapor supply pipe to which the said end section is attached, and a spring-pressed connecting tube connecting the said nipple with the said flexible section of the gasolene supply pipe.
